A similar thing happened with the last update, and at that time I sent all the files in for evaluation through Microsoft - no viruses. It's especially bizarre if you're telling me the main download comes through and the patch doesn't, as everything in the patch is also in the main download! Sigh. My best guess by now is that it's something to do with it being compiled on Microsoft Studio 2008. Some ancient architecture triggering something. Thanks for letting me know, but there's literally nothing I can do to address it. It's a false positive...
